PurposeThe purpose of this paper is to look into the mechanism in which customers involve themselves in omni-channel retail setting and use its advantages.Design/methodology/approachVia an empirical analysis through surveying customers, this paper assesses and confirms the drivers of omni-channel shopping intention within the context of fashion retailing sector in Danang.FindingsThe findings highlight the significance of customer perception of research shopping (including showrooming and webrooming) behaviours, compatibility and risk to their intention towards omni-channel shopping, implying profound understanding of designing effective omni-channel retailing strategy.Originality/valueFrom a theoretical perspective, comprehending customer perception of the omni-channel concept has emerged as an important theme in recent literature as well as in practitioners' reports. Hence, the meaningful contribution of this study is the involvement in the attractive steam of study. From a managerial perspective, this study could offer guidance to retailers or managers about developing a successful omni-channel strategy from a customer point of view.

In the article, we consider the initial boundary value problem for the Gamma equation, which can be derived by transforming the nonlinear Black-Scholes equation for option price into a quasilinear parabolic equation for the second derivative of the option price. We develop unconditionally monotone finite-difference schemes of second-order of local approximation on uniform grids for the initial boundary value problem for the Gamma equation. Two-side estimates of the solution of the scheme are established. By means of regularization principle, the previous results are generalized for construction of unconditionally monotone finite-difference scheme (the maximum principle is satisfied without constraints on relations between the coefficients and grid parameters) of the second-order of approximation on uniform grids for this equation. With the help of difference maximum principle, the two-side estimates for difference solution are obtained at the arbitrary non-sign-constant input data of the problem. A priori estimate in the maximum norm C is proved. It is interesting to note that the proven two-side estimates for difference solution are fully consistent with the differential problem, and the maximal and minimal values of the difference solution do not depend on the diffusion and convection coefficients. Computational experiments, confirming the theoretical conclusions, are given.

PurposeThe purpose of this study is to analyze the effects of integration quality, perceived fluency and assurance quality on brand engagement and trust, and their impacts on brand loyalty in the omnichannel banking setting. It further explores the critical role of personal innovativeness and demographic characteristics as moderating variables for the propositions in the research model.Design/methodology/approachAn online survey of 1,547 respondents was carried out with bank customers located in the three largest cities of Vietnam, who have already used at least two various transactional channels in the past. The results were analyzed by the partial least square-structural equation modeling (PLS-SEM) technique.FindingsThe findings denote that integration quality, perceived fluency and assurance quality significantly influence brand trust. Whereas, brand engagement is only affected by integration quality and perceived fluency. Further, brand engagement and trust are substantiated as critical drivers of brand loyalty in omnichannel banking. Customers with high personal innovativeness produce fewer effects of omnichannel properties on brand engagement and trust than other ones. The research context is found to be a significant moderator for the effect of perceived fluency on brand engagement.Practical implicationsThis study offers several recommendations for bank managers to develop a successful omnichannel strategy that could enhance brand engagement and trust by improving integration quality, maintaining fluency across various channels and assuring security during the transactional process. It suggests various policies to improve the effectiveness of the omnichannel model towards the clients with high innovativeness.Originality/valueThis research extends the social exchange theory (SET) theory by examining the effects of omnichannel properties on brand engagement, trust and loyalty in the banking sector. The moderating role of personal innovativeness and research context is also explored.

We develop unconditionally monotone nite-difference schemes of second-order of local approxi-mation on uniform grids for the initial boundary problem value for the Gamma equation. Two-sideestimates of the solution of the scheme are established. We consider the initial boundary valueproblem for the so called Gamma equation, which can be derived by transforming the nonlinearBlack-Scholes equation for option price into a quasilinear parabolic equation for the second derivativeof the option price, and for its exact solution the two-side estimates are obtained. By means of regu-larization principle, the previous results are generalized for construction of unconditionally monotonenite-difference scheme (the maximum principle is satised without constraints on relations betweenthe coeffcients and grid parameters) of second order of approximation on uniform grids for this equa-tion. With the help of difference maximum principle, the two-side estimates for difference solutionare obtained at the arbitrary non-sign-constant input data of the problem. A priori estimate in themaximum norm C is proved. It is interesting to note that the proven two-side estimates for differ-ence solution are fully consistent with differential problem, and the maximal and minimal values ofthe difference solution do not depend on the diffusion and convection coeffcients. Computationalexperiments, conrming the theoretical conclusions, are given.

We investigate the initial boundary value problem for the Gamma equation transformed from the nonlinear Black-Scholes equation for pricing option to a quasilinear parabolic equation of second derivative. Furthermore, two-side estimates for the exact solution are also provided. By using regularization principle, the unconditionally monotone second order approximation finite-difference scheme on uniform and nonuniform grids is generalized, in that the maximum principle is satisfied without depending on relations of the coefficients and grid parameters. By using the difference maximum principle, we acquired two-side estimates for difference solution for the arbitrary non-sign-constant input data. Finally, we also provide a proof for a priori estimate. It can be confirmed that the two-side estimates for difference solution are completely consistent with the differential problem. Otherwise, the maximal and minimal values of the difference solution is independent from the diffusion and convection coefficients.
